OKLAHOMA CITY — Kevin Durant showed LeBron James how to play the fourth quarter in the NBA Finals.

Durant scored 17 of his 36 points in another nightmarish final period for James and his team, leading a Thunder storm that overwhelmed the Heat and gave Oklahoma City a 105-94 victory over Miami in Game 1 on Tuesday night.

Teaming with Russell Westbrook to outscore the Heat in the second half by themselves, Durant struck first in his head-to-head matchup with James, who had seven points in the final quarter and was helpless to stop the league’s three-time scoring champion.

Westbrook turned around a poor shooting start to finish with 27 points, 11 assists and eight rebounds for the Thunder, keying a strong finish to the third period that gave the Thunder the lead for good.

Durant took over from there.

Scoring in nearly every way possible, Durant finished 12 of 20 from the field and added eight rebounds. He and Westbrook outscored the Heat 41-40 over the final two periods, showing that maybe this time it will be offense that wins championships.

James finished with 30 points, his most in any of his 11 finals games, but had only one basket over the first 8:15 of the fourth, when the Thunder seized control of a game they trailed for all but the final few seconds of the first three quarters.

James averaged just three points in the fourth quarters of the Heat’s six-game loss to Dallas last year, taking almost all the heat for Miami’s finals failure. He was good in this one, Durant was just better.

And when fans chanted “MVP! MVP!” late in the game, they weren’t talking about James, the guy who won the regular-season award.

They meant Durant, who is in a race with James for his first ring — and maybe the title of best player in the game.
